ost::IPV6Mask(3)					     Library Functions Manual						  ost::IPV6Mask(3)

NAME

       ost::IPV6Mask -

       Internet addresses used specifically as masking addresses (such as '
	  255.255.255.0') are held in the IPV6Mask derived object.

SYNOPSIS

       #include <address.h>

       Inherits ost::IPV6Address.

   Public Member Functions
       IPV6Mask (const char *mask)
	   Create the mask from a null terminated ASCII string such as '255.255.255.128'.

   Friends
       __EXPORT IPV6Host operator& (const IPV6Host &addr, const IPV6Mask &mask)
	   Masks are usually used to coerce host addresses into a specific router or class domain.

Detailed Description
       Internet addresses used specifically as masking addresses (such as '
	  255.255.255.0') are held in the IPV6Mask derived object.

       The separate class is used so that C++ type casting can automatically determine when an IPV6Address object is really a mask address object
       rather than simply using the base class. This also allows manipulative operators for address masking to operate only when presented with a
       Masked address as well as providing cleaner and safer source.

Constructor &; Destructor Documentation
   ost::IPV6Mask::IPV6Mask (const char *mask)
       Create the mask from a null terminated ASCII string such as '255.255.255.128'. Parameters:
	   mask null terminated ASCII mask string.

Friends And Related Function Documentation
   __EXPORT IPV6Host operator& (const IPV6Host &addr, const IPV6Mask &mask) [friend]
       Masks are usually used to coerce host addresses into a specific router or class domain. This can be done by taking the Inet Host Address
       object and 'and'ing it with an address mask. This operation can be directly expressed in C++ through the & operator.

       Returns:
	   a internet host address that has been masked.

       Parameters:
	   addr host address to be masked by subnet.
	   mask inetnet mask address object to mask by.
